Auto tech kicked into high gear

Once again, one of the hottest areas of CES 2016 is auto tech. There were nine automakers and 115 suppliers showing off technology, ranging from incremental upgrades on existing models, to futuristic demos that sketch out the transportation world we will soon inhabit (hint: it will involve self-driving cars).

Faraday Future unveiled a racy electric prototype, dubbed the FF Zero 1 Concept, that looks like a cross between a futuristic Batmobile and a very real Porsche 919 Hybrid track demon.
